I have a JVC GR D250AA and have imported a 60 minute tape to my MAC BOOK PRO via iMovie. I would like to put this onto a DVD that I can play in my DVD player. How do I do this? Nothing on the export menu lights up. Also, it says that it is 14 GB, I have DVD-RW which are only 4.2GB....I am sure I am missing something. If anyone could help starting from...once the tape has been imported then...I would really really appreciate it.
